Hi, thanks for creating this, I installed it just now. I notice the link you posted (moonlight-embedded-launcher-0.4.zip) was contained v0.3 inside the folder. I found v0.4 on your github so installed from there.
On the initial install of my LibreELEC, I had to adjust overscan to fit into my TV screen. But when I launch Moonlight, the streaming display doesn't seem to respect that and the edges of screen stretch beyond it. I am streaming my desktop. Also when I quit using Ctrl+Alt+Shift+Q, it doesn't seem to terminate the connection on my computer (meaning I do not get audio on the host back). I'm not sure if this is related to an issue with your code or not. I'm going to try the moonlight embedded on OSMC next. Thanks.
